As much as I seem to argue against the anti hutchinsonians I vote no. Probably a just a liar about Aman to gain a little fame and fortune. That option would have been a relevant choice for this poll-as it would be interesting to see how many people beleive at the very least he was not truthfull about his sighting. I also think fish's idea he was mistaken on the day should be included.
That being said I Beleive he is still one of the better candidates as a suspect for the ripper. One of the least weak of a very weak lot.
